Hello, At the moment I‘m struggling with some newer Dell Precision workstations using „software raid“. The used kernel is Debians 5.10.0-8 which is capable to detect raid-volumes with vroc. The hardware part: 2 hdd (Toshiba 2 TB) 2 SSD (PCI NVMe 512 GB SK Hynix)
Both sets are configured to use raid1. Already installed using whole disk raid1 with pre-installed Windows 10 Pro, so I would like to preserve always partition 1,2 (efi (500MB), msftres (128MB)) and at the end one msftres for recovery (1100MB) so partition 3 should be resized to 380GB (instead of 450GB). Booting fai detects only the ssd and hdd, but not the raid-volumes. At that stage setup-storage fails, because I specified md124 for disk_config-file. When I run: mdadm -A /dev/md/md0 -e imsm /dev/nvme0n1 /dev/nvme1n1 mdadm -A /dev/md/md1 -e imsm /dev/sda /dev/sdb mdadm -- manage /dev/md/md0 -- run mdadm -- manage /dev/md/md1 -- run the raid volumes are running on md126 and md127 and two new volumes are detected using dev names md124 and md125. Deleting /var/run/fai/FAI_INSTALLATION_IN_PROGRESS and calling /etc/init.d/rcS Installs Debian just fine. Grub is installed using grub-efi (it seems without problems), but the created grub.cfg has two options (each of them for one detected Windows installation) Rebooting to the just installed Debian works. Calling „update-grub“ as root detects than only one Windows (on the raid volume) but „destroys“ the running grub.cfg On next reboot grub can‘t find the configfile And the grub prompt showed up: grub> Grub detected than two hdd: hd1 and hd2 Where hd2 is the nvme raid. Calling set root=‘hd2,gpt5’ insmod gzio linux /boot/vmlinuz…. root=LABEL=ROOT ro quiet apparmor=0 ipv6.disable=0 net.ifnames=0 initrd /boot/initrd…. boot Is able to boot the installed Linux. But rerunning update-grub doesn’t help, so I tried to re-run grub-install without success. So two problems: - how can I get fai to automatically detect the existing raid? - how can I get grub-efi to find the grub.cfg after running update-grub later Thanks for any hints Sven Schumacher
